T. M. FLETCHER MUSIC ROLL TERMINAL AND CLASP Filed June 12. 1922 leiafiefl in'ventio i is to provide 1' music roll, adapted roll SRTNY] w 1 slot in the elements and b 0" shown an d i VlEW ot a music r ll Vention with the end 5 a short distance for sh l cl oi suci roll i'ul "sting for holdin igur ig'itudinal with r et through the to spin de ie, showing he iev ral parts or layers mag-uh lied in section for showing the manner of scuring t 1e spring clasp in and Wit/l1 respect to the said lu It is well. ltiown and familiar experience that music rolls tend to become unwound or to become loosely wound on their spools, and the eloy the outer or terminal portions are liable to become rapidly deteriorated in. handling, and -particularly in thrusting into and withdrawing them from tie containing boxes. To overcome this detect 1 provide a spring clasp member connected with and preferably forming a substantial part of the terminal lug, which is normally coiled so as to embrace the wound roll closely, being e astically ilewihle so that it may he rea-cily uncoiled to unwind the roll, and so that it normally comes into clamping relation to the roll as the latter is wound onto the spool.

As shown in the drawing, and as preter ably constructech between the two layers, 2, 2, oi? the terminal lug, which are of any suitand flexible sheet material and which are at ached in the usual manner by gluitg them onto the opposite surfaces of the 111718 ro sheet a strip of elastically flexible material, which may be the. steel watch spring, or preferably as spin as o intenc ed to he indicated by the drawings. a

strip of celluloid, shown at 3, which is normally ()llGCl somewhat less in diameter than the diameter of the wound roll, so to tend to chsp the latter rather closely, as seen in Figure 2. This strip of elastic material reinforces the terminal lug and extends beyond Serial 330. 581575.

In "ew ndi the operator, rsual, holds his hand lightly upon the music roll to cause note sheet to be wound snugly and at the end of the re winding the note sheet hecomes disengaged in the usual way from the take-up pin oi the takeup roll, and as the end is drawn onto the music roll, the clasp normally becomes engage-d around the roll, holding it snugly wound.

I claim 1. A music roll for automatic players; having a terminal lug for i k engagement of the take-up roll of tie player provided with en elastic extension rigidly joined to and continuing integrally iii-011;. its jrnctnre with said lrg, adapted to coil lastically around the roll when the latte; is ,wo' nd to the end thereof on the spool.

2 A spooled note sheet automatic players having teri f for engagement of the take-up roll of the p7 1 provldec. with a spring which is in rigio conjnnct' with. said terminal along; an extent of the lat ter which is flexed the roll in co1n leting the winding 01" the note sheet on the spool and which protruc es in coil "tor-in heyond the end of said terminal which tends to coil elastically around the oil when the not sheet is wound on the spool.

3. In the construction defined in claim 1, foregoing, the terminal comprising tw lay ers of sheet inateial adherent to the opposite sides of tie note sheet extending therebeyond and adherent to each other, the e:-:-

tension being an elastically-flexible strip normally coiled for embracing the roll and means securing the same closely enclosed between said two layers of the terminal lug.

4. in the construction defined in claim 1, foregoing, the extension member being an elastically flexible strip secured to the lug for extending beyond the engagement of the latter with the take-up roll to the extent at least one-half the circumference of the roll. 10 111 testimony whereof l have hereunto set my hand at Chicago Illinois, this 9th day of June, 1922.
